For enhanced safety, the front and middle seat shoulder belts of the Land Rover Discovery have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Blazer doesn’t offer pretensioners for the middle seat belts.
Both the Discovery and Blazer have child safety locks to prevent children from opening the rear doors. The Discovery has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Blazer’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Discovery. But it costs extra on the Blazer.
The Discovery’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Blazer doesn’t offer a driver alert monitor.
Both the Discovery and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, blind spot warning systems and around view monitors.
The Land Rover Discovery weighs 464 to 1134 pounds more than the Chevrolet Blazer. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Discovery comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Blazer’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.
The Discovery’s 6 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Blazer runs out after 100,000 miles.
The Discovery’s 3.0 supercharged V6 produces 147 more horsepower (340 vs. 193) and 144 lbs.-ft. more torque (332 vs. 188) than the Blazer’s standard 2.5 DOHC 4 cyl. The Discovery’s 3.0 supercharged V6 produces 35 more horsepower (340 vs. 305) and 63 lbs.-ft. more torque (332 vs. 269) than the Blazer’s optional 3.6 DOHC V6.
The Discovery’s 3.0 turbo V6 diesel produces 61 more horsepower (254 vs. 193) and 255 lbs.-ft. more torque (443 vs. 188) than the Blazer’s standard 2.5 DOHC 4 cyl. The Discovery’s 3.0 turbo V6 diesel produces 174 lbs.-ft. more torque (443 vs. 269) than the Blazer’s optional 3.6 DOHC V6.
On the EPA test cycle the Discovery Td6 gets better fuel mileage than the Blazer 4WD (21 city/26 hwy vs. 18 city/25 hwy).
The Discovery Diesel’s standard fuel tank has 3.1 gallons more fuel capacity than the Blazer FWD’s standard fuel tank (22.5 vs. 19.4 gallons), for longer range between fill-ups. The Discovery Gas’ standard fuel tank has 1.8 gallons more fuel capacity than the Blazer AWD’s standard fuel tank (23.5 vs. 21.7 gallons).
For better stopping power the Discovery’s brake rotors are larger than those on the Blazer:
The Discovery’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Blazer are solid, not vented.
For better traction, the Discovery’s optional tires are larger than the largest tires available on the Blazer (285/40R22 vs. 265/45R21).
The Discovery’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Blazer RS/Premier’s optional 45 series tires.
For better ride, handling and brake cooling the Discovery has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Blazer. The Discovery’s optional 22-inch wheels are larger than the 21-inch wheels optional on the Blazer RS/Premier.
The Discovery offers an optional full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Blazer, it requires you to depend on a temporary spare, which has mileage and speed limitations, or roadside assistance and a tow-truck.
For a smoother ride and more stable handling, the Discovery’s wheelbase is 2.3 inches longer than on the Blazer (115 inches vs. 112.7 inches).
The Discovery offers optional seating for 7 passengers; the Blazer can only carry 5.
The Discovery has .2 inches more front headroom, 2.2 inches more front hip room, 1.3 inches more front shoulder room, .4 inches more rear headroom, 1.5 inches more rear hip room and .8 inches more rear shoulder room than the Blazer.
For enhanced passenger comfort on long trips the Discovery’s middle row seats recline. The Blazer’s rear seats don’t recline.
Flexibility is maximized at the game, campground or a drive-in theatre in the Discovery when its optional tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The Blazer doesn’t offer tailgating seats.
The Discovery’s cargo area provides more volume than the Blazer.

The Discovery’s standard towing capacity is much higher than the Blazer’s (8201 vs. 1500 pounds).
The engine in the Discovery is mounted longitudinally (North-South), instead of sideways, as in the Blazer. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.
Unlike the driver-only memory system optional at extra cost in the Blazer (except L/LT), the Discovery HSE/HSE Luxury has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.
The Discovery HSE/HSE Luxury offers an optional heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Blazer doesn’t offer a heads-up display.
The Discovery’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Blazer’s passenger windows don’t close automatically.
If the windows are left open on the Discovery the driver can close them all from a distance using the remote. The driver of the Blazer can only close the windows from inside the vehicle, with the ignition on.
The Discovery’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Blazer’s manually variable intermittent wipers have to be constantly adjusted.
Heated windshield washer nozzles are optional on the Discovery to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Blazer doesn’t offer heated windshield washer nozzles.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Discovery offers available headlight washers to keep headlight output high. The Blazer doesn’t offer headlight washers.
To help drivers see further while navigating curves, the Discovery HSE/HSE Luxury offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Blazer doesn’t offer cornering lights.
When the Discovery is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Blazer’s mirrors don’t automatically adjust for backing.
Optional air conditioned the front and second row seats keep the Discovery’s passengers comfortable and take the sting out of hot leather in summer. The Blazer doesn’t offer air-conditioned seats in the rear.
The Discovery’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Blazer doesn’t offer an automated parking system.
